摘要
提出了岩石声发射规律数值模拟的基本设想和框架，并以有限单元法为例就具体实施的几个关键问题作了简述，包括单元的划分、单元参数的赋值、声发射率的计算。本文给出了一个计算实例，所得结果包括岩石声发射的时间序列和空间序列分布。
The basic idea and framework are presented for the numerical simulation of AE in rock failure. Some important problems are discussed briefly with the example of finite element method , such as discretization of elements, assignment of element parameters, and calculation of AE ratio. A practical computation example is given, from whose results the AE sequences for time and space are obtained.
